工作小结（十八）-Gridview使用二[在不同的地方查找Textbox和主键]

在不同的地方查找Textbox和主键:

1.在FSLGridView1_RowDataBound中查找模板列中的TextBox

 1  protected   void  FSLGridView1_RowDataBound( object  sender, GridViewRowEventArgs e)
 2          {
 3               // 判断当前行是否是数据行
 4               if  (e.Row.RowType  ==  DataControlRowType.DataRow)
 5              {
 6                  TextBox txt1  =  (TextBox)e.Row.FindControl( " txtDBFix " );
 7                  txt1.Text  =  e.Row.Cells[ 1 ].Text; 
 8              }
 9          }

上例：将第0列的值赋到txtDbFix的文本框列中,另外获取主键ID：int ID = this.GridView1.DataKeys[e.Row.RowIndex].Value;

运用：把GridView中某列的值赋到模板列中的TextBox中去。

 

2.在FSLGridView1_RowCommand中查找模板列中的TextBox和主键

前台：

<asp:TemplateField HeaderText="关闭提醒">
     <ItemTemplate>
         <fsl:FSLButton runat="server" ID="FSLButClose" SkinID="fslButton" Text="关闭提醒" CommandName="updateremind"
                                CommandArgument='<%# DataBinder.Eval(Container,"RowIndex") %>' />
      </ItemTemplate>
 </asp:TemplateField>

 后台：

 

代码

protected   void  FSLGridView3_RowCommand( object  sender, GridViewCommandEventArgs e)
{ 
    if  (( string )e.CommandName  ==   " updateremind " )
   {
       RemindInfo remindInfo  =   new  RemindInfo();

        int  index  =  Convert.ToInt32(( string )e.CommandArgument);
       remindInfo.updateByRmguid(FSLGridView3.DataKeys[index].Value.ToString());

       ClientScript.RegisterStartupScript(GetType(),  "" ,  " <script language='javascript'>alert('关闭成功！');window.location.href='MyJobTable.aspx';</script> " );
       this .FSLGridView3.DataBind();
   }
}

 

运用：GridView中每行修改数据

 

3.在普通的按钮中查找模板列中的TextBox和主键

 1    protected   void  FSLButDbUpdate_Click( object  sender, EventArgs e)
 2          {
 3               foreach  (GridViewRow row  in  FSLGridView1.Rows)
 4              {
 5                   if  (row.RowType  ==  DataControlRowType.DataRow)
 6                  {
 7                       if  (row.RowState  ==  DataControlRowState.Normal  ||  row.RowState  ==  DataControlRowState.Alternate)
 8                      {
 9                          System.Web.UI.WebControls.TextBox TextBox1  =  (System.Web.UI.WebControls.TextBox)row.FindControl( " txtDBFix " );
10                          System.Web.UI.WebControls.TextBox TextBox2  =  (System.Web.UI.WebControls.TextBox)row.FindControl( " txtTotalDBFix " );
11 
12                           if  ( string .IsNullOrEmpty( this .ddlDay.SelectedValue))
13                          {
14                               if  ( string .IsNullOrEmpty( this .ddlMonth.SelectedValue))
15                              {
16                                  tblTPCCSummeryUtitiy.UpdateDBYear(FSLGridView1.DataKeys[row.RowIndex].Value.ToString(), TextBox1.Text,  1 , TextBox2.Text,  1 );
17                              }
18                               else
19                              {
20                                  tblTPCCSummeryUtitiy.UpdateDBMonth(FSLGridView1.DataKeys[row.RowIndex].Value.ToString(), TextBox1.Text,  1 , TextBox2.Text,  1 );
21                              }
22                          }
23                           else
24                          {
25                              tblTPCCSummeryUtitiy.UpdateDBDay(FSLGridView1.DataKeys[row.RowIndex].Value.ToString(), TextBox1.Text,  1 , TextBox2.Text,  1 );
26                          }
27 
28                      }
29                  }
30              }
31 
32               this .FSLGridView1.DataBind();
33          }
